Coronavirus : specific pathogen shrimp programs – yes there are several out there….
About facts and myths…..’The original shrimp stock was obtained using rigorous screening of captured wild shrimp for selection of individuals naturally free of major shrimp pathogens.”
Not true!
Original shrimp stock were cultured PLs and supplied by Prawnmaster to Dr Lightner at APL, Arizona in 1989 from his facility in Mexico.
They were 16,000 PL’s spawned from artificially inseminated vannamei in Mexico and passed through a proprietary natural selection program on a special diet and an extremely low survival rate.
These were declared SPF by APL (personal communications and visits) and sent to OI in Hawaii. The female Griselda became famous.
There is only one country in the world that had the stranglehold on live global shrimp movements under the UN OIE and that is the USA. A country where Pacific vannamei is not even endemic.
This has led to the manipulation of trade and the promotion of US interests in specific shrimp pathogen programs. USA is not even a shrimp producer – even though that was stated aim or the US NMFS Shrimp Consortium’s program back in the late 1980’s.
Ecuador was the first country that US targeted for its genetics program and it failed miserably. Ecuador has since gone on to develop a more sensible program – with increased resulting production – whereas USA has still zero real shrimp farming.
Coronavirus – parallels in the prawnbook. Impossible to make the world SPF.
Now that ET building blocks to life have been found
There is nothing to fear but fear itself.
Impossible to make world SPF.
Which is why initially it failed with vannamei shrimp and was re-branded shrimp high health for the commodity mass market.
We all know the development of the US led shrimp SPF and the French led shrimp SPR (plus other sub derivatives up to APE) programs.
SPF (type of quaranteen and self isolation) is all about survival. More elitist but grow out isolated in climate controlled and genetically manipulated environments.
SPR is about developing resistance rather than exclusion.
